GPR Targets and Clutter Discrimination using Normalised Superimposition

摘要

A new form of the Normalised Superimposition (NSI) scheme is used to produce improved GPR B-scans. The scheme is seen to enhance the discrimination between targets in the presence of many small clutter targets, a situation often encountered in GPR work. It is also observed that the use of wideband or multi band measurement can greatly improve the identification and discrimination of targets and clutter.
